</span></span> * @class Ext.data.JsonStore
 * @extends Ext.data.Store
 * &lt;p&gt;Small helper class to make creating {@link Ext.data.Store}s from JSON data easier.
 * A JsonStore will be automatically configured with a {@link Ext.data.JsonReader}.&lt;/p&gt;
 * &lt;p&gt;A store configuration would be something like:&lt;pre&gt;&lt;code&gt;
var store = new Ext.data.JsonStore({
    // store configs
    autoDestroy: true,
    url: 'get-images.php',
    storeId: 'myStore',
    // reader configs
    root: 'images',
    idProperty: 'name',
    fields: ['name', 'url', {name:'size', type: 'float'}, {name:'lastmod', type:'date'}]
});
 * &lt;/code&gt;&lt;/pre&gt;&lt;/p&gt;
 * &lt;p&gt;This store is configured to consume a returned object of the form:&lt;pre&gt;&lt;code&gt;
{
    images: [
        {name: 'Image one', url:'/GetImage.php?id=1', size:46.5, lastmod: new Date(2007, 10, 29)},
        {name: 'Image Two', url:'/GetImage.php?id=2', size:43.2, lastmod: new Date(2007, 10, 30)}
    ]
}
 * &lt;/code&gt;&lt;/pre&gt;
 * An object literal of this form could also be used as the {@link #data} config option.&lt;/p&gt;
 * &lt;p&gt;&lt;b&gt;*Note:&lt;/b&gt; Although not listed here, this class accepts all of the configuration options of
 * &lt;b&gt;{@link Ext.data.JsonReader JsonReader}&lt;/b&gt;.&lt;/p&gt;
 * @constructor
 * @param {Object} config
 * @xtype jsonstore
